Hiroi – Seiji is said to have the very best eye for Tategoi in the world. He is mainly a dealer but does breed some superb Kohaku from a Murata bloodline.

Other breeders in the area are always aware when Hiroi San drops in to have a look at the new tosai, or the Nissai they have, Buying their best koi and then growing them in huge mudponds in the Yamakoshi area. Many famous koi have come from Hiroi-Seiji over the years, ranging from big show winners to special odd ball koi, such as a 95cm Shiro Utsuri which should have won the Nogyosai a few years ago, his eye is amazing. At his facility he has 2 large ponds, 1 for koi up to 3 years old, then in the main pond, the jumbo koi are on show. Many varieties , and mostly all excellent specimens. His own bred Kohaku and some Showa have really come on well, sizes to rival any other breeder in the world at Tosai and Nissai, I have seen one of his Nissai at 65cms which is incredible.

Hiroi San is very famous around the Niigata area, and is always on hand to help with harvesting of some of the major koi hobbyists in Japan’s koi. When his koi are harvested its always a huge party of other breeders there, ready to see the koi he has bought for them to come out, most of them get very upset!
